I think I've gotten the hang of the switch side of things now 
Had to build the LED part of the circuit to get it, far from what I've seen in my books this one.
I just have to check how much of a bounce my sensors have to set the read interval of the pin.
Still a lot of job left to rewrite the fade in "1 line at a time" but I think i'm on the right track here...
Thanks for all the help, hopefully my next attempt will be more successful
Thankfully the RGBfade won't need any stop command, just a counter.
